The last page in a pamphlet available in Japanese cinema where "Gundam UC" Episode 1 was shown recently reveals the title and release date of Episode 2.
OVA Episode 2 "The Red Comet" will be released in Fall this year. The mentioned page has the image of Full Frontal, as well as Sinanju on it.
The return of the Red Comet! ^^
Images of the pamphlet:
Seems like Angelo Sauper will be debuting in Episode 2 as well.
